What is the difference between SOAP 1 1 SOAP 1 2 HTTP GET HTTP POST methods for Android

Question

I am working on a code for SOAP Web services, I would like to know the variations in SOAP 1.1, SOAP 1.2, HTTP GET & HTTP POST methods for Android, and which is the preferred one among them. Please site out a sample of its usage URL or its code.

Thanks

Following document published by W3C also describes the differences between SOAP 1 1 and 1 2      From SOAP 1 1 to SOAP Version 1 2 in 9 points

Differences in SOAP versions  Both SOAP Version 1 1 and SOAP Version 1 2 are World Wide Web Consortium  W3C  standards  Web services can be deployed that support not only SOAP 1 1 but also support SOAP 1 2  Some changes from SOAP 1 1 that were made to the SOAP 1 2 specification are significant  while other changes are minor   The SOAP 1 2 specification introduces several changes to SOAP 1 1  This information is not intended to be an in-depth description of all the new or changed features for SOAP 1 1 and SOAP 1 2  Instead  this information highlights some of the more important differences between the current versions of SOAP   The changes to the SOAP 1 2 specification that are significant include the following updates  SOAP 1 1 is based on XML 1 0  SOAP 1 2 is based on XML Information Set  XML Infoset   The XML information set  infoset  provides a way to describe the XML document with XSD schema  However  the infoset does not necessarily serialize the document with XML 1 0 serialization on which SOAP 1 1 is based   This new way to describe the XML document helps reveal other serialization formats  such as a binary protocol format  You can use the binary protocol format to compact the message into a compact format  where some of the verbose tagging information might not be required   In SOAP 1 2   you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units  The HTTP binding that is specified in SOAP 1 2 - Part 2 uses XML 1 0 as the serialization of the SOAP message infoset   SOAP 1 2 provides the ability to officially define transport protocols  other than using HTTP  as long as the vendor conforms to the binding framework that is defined in SOAP 1 2  While HTTP is ubiquitous  it is not as reliable as other transports including TCP IP and MQ  SOAP 1 2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability  WS-I  profiles  The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1 2 implementations  SOAP with Attachments API for Java  SAAJ  can also stand alone as a simple mechanism to issue SOAP requests  A major change to the SAAJ specification is the ability to represent SOAP 1 1 messages and the additional SOAP 1 2 formatted messages  For example  SAAJ Version 1 3 introduces a new set of constants and methods that are more conducive to SOAP 1 2  such as getRole    getRelay    on SOAP header elements  There are also additional methods on the factories for SAAJ to create appropriate SOAP 1 1 or SOAP 1 2 messages  The XML namespaces for the envelope and encoding schemas have changed for SOAP 1 2  These changes distinguish SOAP processors from SOAP 1 1 and SOAP 1 2 messages and supports changes in the SOAP schema  without affecting existing implementations  Java Architecture for XML Web Services  JAX-WS  introduces the ability to support both SOAP 1 1 and SOAP 1 2  Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time  there became a need to represent this message in its appropriate SOAP context  In JAX-WS  a number of additional enhancements result from the support for SAAJ 1 3   There is not difine POST AND GET method for particular android    but all here is differance  GET The GET method appends name value pairs to the URL  allowing you to retrieve a resource representation  The big issue with this is that the length of a URL is limited  roughly 3000 char  resulting in data loss should you have to much stuff in the form on your page  so this method only works if there is a small number parameters    What does this mean for me  Basically this renders the GET method worthless to most developers in most situations  Here is another way of looking at it  the URL could be truncated   and most likely will be give today s data-centric sites  if the form uses a large number of parameters  or if the parameters contain large amounts of data  Also  parameters passed on the URL are visible in the address field of the browser  YIKES     not the best place for any kind of sensitive  or even non-sensitive  data to be shown because you are just begging the curious user to mess with it   POST The alternative to the GET method is the POST method  This method packages the name value pairs inside the body of the HTTP request  which makes for a cleaner URL and imposes no size limitations on the forms output  basically its a no-brainer on which one to use  POST is also more secure but certainly not safe  Although HTTP fully supports CRUD  HTML 4 only supports issuing GET and POST requests through its various elements  This limitation has held Web applications back from making full use of HTTP  and to work around it  most applications overload POST to take care of everything but resource retrieval   Link to original IBM source
